Interfacial electronic interaction of atomically dispersed IrClx on ultrathin Co(OH)(2)/CNTs for efficient electrocatalytic water oxidation

The exploration of highly-efficient oxygen evolution reaction (OER) electrocatalyst with well-defined structure to understand specific structure-performance relationship is crucial to meet the requirement of water-splitting. Herein, we firstly used atomically dispersed IrClx to uniformly decorate ultrathin Co(OH)(2) nanosheets to dramatically improve electrocatalytic activity. The synthesized IrClx-Co(OH)(2) nanosheets/carbon nanotubes (CNTs) exhibits an overpotential of 230 mV to reach 10 mA/cm(2), which was much enhanced compared to that of pristine Co(OH)(2)/CNTs (308 mV) and commercial benchmark IrO2(309 mV). X-ray absorption fine structure and density functional theory simulations demonstrate strong interfacial interaction between IrClx and Co(OH)(2) nanosheets via the Cl-Ir-O and Ir-Cl-Co bond can efficiently boost its electronic conductivity. The accelerated charge transfer promotes the formation of more positively charged O atoms around cobalt centers, which is beneficial for the deprotonation on IrClx-Co(OH)(2) and makes the catalyst facilitate OER.

A new facile method for spin-labeling of oligonucleotides

A new facile method for spin-labeling suitable for DNA and RNA oligonucleotides is presented. The nitroxide 3-ethenyl-2,2,5,5-tetramethyl-pyrrolin-1-yloxy was directly introduced during automated solid-phase synthesis by a Pd(0) cross coupling reaction. The main advantages of this procedure are the small amount of spin-label needed for the derivatisation of the oligonucleotide and the high coupling efficiency on the solid phase.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.

Multicolor Activatable Raman Probes for Simultaneous Detection of Plural Enzyme Activities

Raman probes based on alkyne or nitrite tags hold promise for highly multiplexed imaging. However, sensing of enzyme activities with Raman probes is difficult because few mechanisms are available to modulate the vibrational response. Here we present a general strategy to prepare activatable Raman probes that show enhanced Raman signals due to electronic preresonance (EPR) upon reaction with enzymes under physiological conditions. We identified a xanthene derivative bearing a nitrile group at position 9 (9CN-JCP) as a suitable scaffold dye, and synthesized four types of activatable Raman probes, which are targeted to different enzymes (three aminopeptidases and a glycosidase) and tuned to different vibrational frequencies by isotope editing of the nitrile group. We validated the activation of the Raman signals of these probes by the target enzymes and succeeded in simultaneous imaging of the four enzyme activities in live cells. Different cell lines showed different patterns of these enzyme activities.

Separation of Tire Rubber Overlapping Terahertz Spectra Using Non-Negative Matrix Factorization of Spectral Feature Constraints

With the deepening of the concept of green tires, the effective composition of tire rubberis directly related to the qualification of rubber. But tire rubber is a black analysis system for the inspection department, and it’ sexceedingly crucialto accurately detect rubber components by the existing methods. Terahertz time-domain spectroscopy (THz-TDS) technology has been successfully applied to material detection and analysis, but the terahertz spectral data observed from a complex sample of rubber represents the comprehensive results of several interrelated components or interaction of characteristic components in many cases, where as the actual information contained in the raw data may overlap, which will conversely affect the analysis of the components in the rubber mixture. In order to solve the problem of terahertz spectral overlap, the characteristics of continuous smoothing of terahertz spectral matrix and sparse concentration matrix are combined this paper, then the 2 norms with smoothing characteristics and the 1/2 norm with sparsity characteristics into the non-negative matrix factorization method is introduced, which are applied to the separation of terahertz aliased spectra, so as eparation method of terahertz aliasing spectral based on spectral feature Constrained Non-negative Matrix Factorization (CNMF) is proposed. Firstly, nitrile-butadiene rubber combined with vulcanization accelerator 2-Mercaptobenzothizzole(MBT) to form a binary mixture in diverse proportions, and it combined with vulcanization accelerators MBT and tetramethyl thiuram monosulfide (TMTM) to form a ternary mixture in different proportions. Then the terahertz time domain spectrum of all samples ismeasured by terahertz spectroscopy system, which the measured data is subjected too btain a corresponding absorbance spectrum. Further, principal component analysis is performed on the obtained spectral matrix to initially determine the number of components of the mixture. Finally, the Non-negative Matrix Factorization (NMF), Non-negative Matrix Factorization based on pure variables initialization(PNMF) and CNMF methods are used to the decomposition of the mixture data matrix and spectral analysis of the aliased spectrum. The results show that the separation effect of the CNMF algorithm is better than that of NMF and PNMF method, and the corresponding results of the characteristic absorption peak are accurate. In addition, the correlation coefficients of separation results for different component mixtures are higher than 89%, and the spectral angles are less than 0.5 with a higher reduction degree of purity spectrum. Therefore, the constrained non-negative matrix factorization algorithm is introduced into the separation of terahertz aliasing spectra, which is preferable to extract the characteristic information of single components in complex mixtures and provides a better foundation for the qualitative analysis and quantitative calculation of subsequent terahertz multicomponent mixtures as well as the considerable research prospects in the field of quality testing of green tires and rubber.

The enantioselective synthesis of the R-enantiomer of the marine natural product (S)-ypaoamide (5) is reported. The synthesis features both a flexible racemization-free approach to the 5-substituted 3-pyrrolin-2-one segment, and a lipase (CCL)-promoted deacetylation reaction to reach the orthogonal deprotection. Through this work the absolute configuration of the natural ypaoamide was determined as S.

Discovery and Surprises with Cyclizations, Cycloadditions, Fragmentations, and Rearrangements in Complex Settings

We discuss a number of synthesis routes to complex natural products recently reported from our group. Although the structures are quite varied, we demonstrate the research endeavor as a setting to examine the implementation of cyclizations, cycloadditions, rearrangements, and fragmentations. We showcase how the various transformations enabled access to key core structures and thereby allowed the rapid introduction of complexity. Two different routes to (-)-mitrephorone A, the first case discussed, led to the use of Koser’s reagent to effect oxetane formation from diosphenol derivatives. Even though the Diels-Alder cycloaddition reaction represents one of the workhorses of complex molecule synthesis, there are opportunities provided by the complexity of secondary metabolites for discovery, study, and development. In our first approach to (-)-mitrephorone A, Diels-Alder cycloaddition provided access to fused cyclopropanes, while the second synthesis underscored the power of diastereoselective nitrile oxide cycloadditions to access hydroxy ketones. The successful implementation of the second approach required the rigorous stereocontrolled synthesis of tetrasubstituted olefins; this was accomplished by a highly stereoselective Cr-mediated reduction of dienes. The diterpenoid (+)-sarcophytin provided a stage for examining the Diels-Alder cycloaddition of two electron-deficient partners. The study revealed that in the system this unusual combination works optimally with the E,Z-dienoate and proceeds through an exo transition state to provide the desired cycloadduct. Our reported pallambin synthesis showcased the use of fulvene as a versatile building block for the core structure. Fulvene decomposition could be out competed by employing it as a diene and using a highly reactive dienophile, which affords a bicyclic product that can in turn be subjected to chemo- and stereoselective manipulations. The synthesis route proceeds with a C-H insertion providing the core structure en route to pallambin A and B. The studies resulting in our synthesis of gelsemoxonine highlight the use of the acid-catalyzed rearrangement/chelotropic extrusion of oxazaspiro[2.4]heptanes to access complex beta-lactams, which are otherwise not readily prepared by extant methods in common use. Mechanistic investigations of the intriguing ring contraction supported by computational studies indicate that the reaction involves a concerted cleavage of the N-O bond and cyclopropane ring opening under the extrusion of ethylene. The synthesis of guanacastepenes focused on the use of cyclohexyne in [2+2]-cycloadditions with enolates. The resulting cyclobutene can be enticed to undergo ring opening to give a fused six-seven ring system. The cycloinsertion reaction of cyclohexyne developed for the first time proves useful as a general approach to complex fused ring systems.

A Unique Mdm2-Binding Mode of the 3-Pyrrolin-2-one- and 2-Furanone-Based Antagonists of the p53-Mdm2 Interaction

The p53 pathway is inactivated in almost all types of cancer by mutations in the p53 encoding gene or overexpression of the p53 negative regulators, Mdm2 and/or Mdmx. Restoration of the p53 function by inhibition of the p53-Mdm2/Mdmx interaction opens up a prospect for a nongenotoxic anticancer therapy. Here, we present the syntheses, activities, and crystal structures of two novel classes of Mdm2-p53 inhibitors that are based on the 3-pyrrolin-2-one and 2-furanone scaffolds. The structures of the complexes formed by these inhibitors and Mdm2 reveal the dimeric protein molecular organization that has not been observed in the small-molecule/Mdm2 complexes described until now. In particular, the 6-chloroindole group does not occupy the usual Trp-23 pocket of Mdm2 but instead is engaged in dimerization. This entirely unique binding mode of the compounds opens new possibilities for optimization of the Mdm2 p53 interaction inhibitors.
